K Application led Januaryv21,f 1927,Seria1-No.p162,6`57, and in Great Britain `January 26, 19203.

p This invention relates to improvements in'y .i curtain suspension devices comprising runners, consisting of rollers provided with hooksor llikelittings freely suspended from the rollers,-and groovedv or channelled tracks to provide'upper and lower' races in which the rollers run. p l y The object of theinvention is to provide an improved device of this kind which can be economically manufactured, easily fitted up by unskilled persons, and will be efficient in use,- the runners working easily without binding even if the curtain be pulled outwardly or inwardly as well as sideways.

A curtain suspension device according to the invention comprises a race having upper and lower channels and-runners provided with disc rollers with rounded'peripheries, which extend into. both channels and have a running engagement therein (i. e. a running clearance is provided), the channels being formed so that clearance is provided at the sides of the peripheries of the disc rollers to permit them to tilt in accordance with the pull of the curtains, and so that the disc rollers which are guidedbetween both channels, are prevented from leaving said channels and remain normal vto the surfaces thereof irrespective of the direction of pull on the curtains. Y

The race, is preferably formed Vof, thin rolled, drawn or pressed metal, and with a rear web connecting the upper and lower channels, the web being punched or drilled for screws or otherwise adapted for attachment to a window frame or other support. The Web is preferably ytrough shaped or koffset suiiiciently to provide a recess for Vthe heads of the screws so that they are clear of the runners and to provide a section affording adequate strength.

' In the accompanying drawings Figure 1 is `a cross sectional elevation showing on a very enlarged scale one form of device according to the invention applied to a window frame.

Figure 2 is a front elevation of a similar form .drawn on a less enlarged scale.

Figure 3 is asimilar section tovFigure 1 but showing a modified form of roller.

In the form of device illustrated a race is rolled or drawn in thin steel, brass or other metal with a cross section such as indicated in Figure 1, namely with upper and lower channelled portions 1, 1, connected by a rear vWashers 7 and S'are mounted one on each side of web `2, 'having it at intervalsfor screws 3.

,Each runner comprises a disc roller ,4 fr eely mounted on a hanger arm,"such as a wire which is'bent downwardly` to form a hook 6 for they attachment of the curtain. on thewire 5, the disc roller` 4, the washer 7 being forced tightly on tothe wire and the end of the wire Vbeing riveted or burred over to hold the washer 8 in position. Very slight clearance is left between the washers and the disc roller. \The discroller 4 is Slightly rounded on its periphery.

The inner surface of the channelled por- 110165 punhed' or Einlined inv tions 1, 1, are curved to a radius which is i the radius of the disc roller.

-Clearance is left between the sides of the disc roller and a lip 9 and a-ridge 10. By these means the disc roller which is guided between both channels is free rto run properly without binding besides being pre-vented vfrom Vleaving the channels, even if the runner be tilted due to the curtain being pulled outwardly 0r inwardly as well as sideways, as the roller is always normal tothe inner surface of the channels, it being understood of course, that a. slightv running clearance is provided for the disc roller.

The washer 7 and thewire 5 are shaped to avoid Contact with the lower lip 9 in the 'event of the curtain being pulled inwardly.

well backfrom the channelled portions so that ample clearance is left between the heads of the screws 3 and the disc roller.

The web maybe made separate from the channelled portions which may be secured to a` solid, perfc-ratedor other web or back portion which may be of metal, wood or other material, or they may be connected at intervals only by strips'or wires provided with holes or loops or eyelets for the reception of the screws by which the race is to be secured to the window frame, brackets or other support.

- ting ends may be enclosed in jointing` pieces Lengths of a race of the form illustrated may be setend to end and if 'desired the abut-` curved pieces or elbows of the proper cross i section.

I claim:

A curtain suspension device comprising a race formed oi upper and lower channel members or' arcuate cross section, and curtain runners each including a hanger arm and a roller of Substantially similar radius as that of the channels to permit running engagement oftherrol-ler with the channels in various tilted positions of the roller, said channel members having outer lips and inner ridges to limit the tilting movements 4ofy the roller and prevent its separation from the race, the limited tilting movement ofthe' roller preventing contact between the hanger arm and the channel members in' any posi-1 tion of the roller.

In testimony whereof I have signed my name to this speciiication.
